Let, rainfall of last year = x

A.T.Q,

x/2 - 3.2 = 18.6

x/2 = 18.6+3.2

x/2 = 21.8

x = 21.8*2

x = 43.6

denis23 [38]

Answer:

  replace recipe quantities:

  1/4 ⇒ 5/8; 1/2 ⇒ 1 1/4; 1 ⇒ 2 1/2; 1 1/2 ⇒ 3 3/4; 2 ⇒ 5

Step-by-step explanation:

The given recipe serves 4, so must be multiplied by 10/4 = 5/2 to make it make 10 servings.

The numbers in the recipe (ignoring units or ingredients) are ...

  1/4, 1/2, 1, 1 1/2, 2

Each of these numbers needs to be multiplied by 5/2 to get the number for the larger recipe.

  1/4 × 5/2 = 5/8

  1/2 × 5/2 = 5/4 = 1 1/4

  1 × 5/2 = 5/2 = 2 1/2

  (1 1/2) × 5/2 = 3/2 × 5/2 = 15/4 = 3 3/4

  2 × 5/2 = 5

Then, to make the larger recipe, rewrite it with the quantities replaced as follows:

  old value ⇒ new value

  1/4 ⇒ 5/8

  1/2 ⇒ 1 1/4

  1 ⇒ 2 1/2

  1 1/2 ⇒ 3 3/4

  2 ⇒ 5

__

For example, 1 1/2 lbs of fresh tomatoes ⇒ 3 3/4 lbs of fresh tomatoes

_____

<em>Additional comment</em>

If you actually want to create the recipe, you may find it convenient to use a spreadsheet to list quantities, units, and ingredient names. Then you can add a column for the quantities for a different number of servings, and let the spreadsheet figure the new amounts. (A spreadsheet will compute quantities in decimal, so you will need to be familiar with the conversions to fractions--or use metric quantities.)

So this has to do with permutations and honestly I need an explanation on how I can figure these out.
AnnZ [28]
Well, the answer quite simple ....there are 4! ways to arrange these numbers...and as 4! = 4*3*2*1 = 24

hence 24 is the correct answer....


u can also remember it by theorem of multiplication as.....in first place (I.e. first code can be any no. out of 4,5,2&7 ....so 4*.....

as first place is acquired by a certain no. that leaves three no. to fill third place and when third place I'd occupied it leaves 2 numbers to fill second place and lastly only one no. to fill the last place .....so it's result will be like 4*3*2*1.



I know this is pretty much confusing ....but still I tried my best....

if anything troubles u here feel free to ask me

How do you Convert feet to metres<br>​
poizon [28]

The conversion of feet to meters is obtained by multiplying 1 foot = 0.3048 meters.

<h3>What are the basic measurements for length?</h3>

Foot, inches, centimeters, and meters are the basic measuring units for length.

<h3>What are the basic conversions?</h3>

The basic conversions are:

1 kilometer = 1000 meters

1 meter = 100 cm

1 cm = 10 mm

1 mm = 0.03937 inch

1 inch = 0.0833 feet.

<h3>How to convert feet to meters?</h3>

According to the international system of units,

1 foot = 12 inches ...(1)

But we know,

1 inch = 25.4 mm, 1 mm = 0.1 cm, and 1 cm = 0.01 m

By substituting all of these in equation (1), we get

1 foot = 12(25.4 mm)

         = 304.8 mm

         = 304.8 (0.1 cm)

         = 30.48 cm

         = 30.48(0.01 m)

         = 0.3048 meters

Therefore, 1 foot = 0.3048 meters.
